RESOLUTION

To resolve this problem, follow these steps:

Click Start. In the Start Search box, type Notepad. Right-click Notepad, and then click Run as administrator.

Note If you are prompted for an administrator password or for a confirmation, type the password, or click Continue.
On the File menu, click Open. In the File name box, type %windir%\system32\inetsrv\config\applicationhost.config, and then click Open.
In the ApplicationHost.config file, locate the <requestLimits> node.

<requestLimits maxAllowedContentLength ="<length>" />
Save the ApplicationHost.config file.
